O God, your mercy knows no bounds and the treasure of your goodness is
infinite..." (Prayer after the "Te Deum" Hymn)

"The paschal mystery is the culmination of this revealing and
effecting of mercy, which is able to justify man, to restore justice in
the sense of that salvific order which God willed from the beginning in
man, and through man, in the world" (Encyclical Letter Dives in
misericordia, n. 7).

"And so with provident pastoral sensitivity and in order to
impress deeply on the souls of the faithful these precepts and teachings
of the Christian faith, the Supreme Pontiff, John Paul II, moved by the
consideration of the Father of Mercy, has willed that the Second Sunday
of Easter be dedicated to recalling with special devotion these gifts of
grace and gave this Sunday the name, "Divine Mercy Sunday"
(Congregation for Divine Worship and the Discipline of the Sacraments,
Decree Misericors et miserator, 5 May 2000).
